A wafer thinning system and method are disclosed that includes grinding away substrate material from a backside of a semiconductor device. A current change is detected in a grinding device responsive to exposure of a first set of device structures through the substrate material, where the grinding is stopped in response to the detected current change. Polishing repairs the surface and continues to remove an additional amount of the substrate material. Exposure of one or more additional sets of device structures through the substrate material is monitored to determine the additional amount of substrate material to remove, where the additional sets of device structures are located in the semiconductor device at a known depth different than the first set.

The present invention provides a method and system for depicting an online map of a route along with any incidents on the route. To create the map, a consumer first provides the origination and destination addresses of the route, then a proposed route is provided for their approval. The consumer may modify the proposed route or accept it. Next, the route is analyzed to determine if any incidents have occurred upon it. This analysis comprises preparing the route by creating regions of interest around segments composing the route, examining if any traffic incidents fall within one or more of the regions of interest, and determining for those incidents if the incident is closer than a threshold value to any segment on the route. The final route along with any incidents on the route is then depicted for the consumer.

The present invention enables typing on a touchscreen without the need for the user to accurately hit each key on an onscreen keyboard. The relative distance and direction between each letter of a word on a virtual keyboard (visible or invisible) is used to uniquely identify the desired word by comparing parameters with those pre-stored in a word database. This means the user may begin typing at any location on the screen, without being constrained to a pre-determined location of an onscreen keyboard. It also means the size of the virtual onscreen keyboard may be determined by the user's typing pattern. Various disambiguation strategies can be applied to this typing approach to allow the user to be imprecise.

The processing system may also facilitate customers fiscal management through the communication of data necessary to practice the instant invention.

A technique for estimating the location of a wireless terminal at an unknown location in a geographic region is disclosed. The technique is based on the recognition that there are traits of electromagnetic signals that are dependent on topography, the receiver, the location of the transmitter, and other factors. For example, if a particular radio station is known to be received strongly at a first location and weakly at a second location, and a given wireless terminal at an unknown location is receiving the radio station weakly, it is more likely that the wireless terminal is at the second location than at the first location.
